Fatwa Question or Essay Title: 
Why is the building of temples and churches and the propagation of any religion other than Islam not allowed in Islamic countries like Saudi Arabia?

There is no other religious scripture on the face of the earth besides the Quran which says that only its religion is true, correct and acceptable to Almighty God and that all the other religions are false and hence not acceptable to Almighty God.
